UNITED STATES HENRY C. RIESBOL, OF NEW' YORK, N. Y.

CONCRETE BUILDING FORM.

Application led February 25, 1925. Serial No. 11,596.

To all 'whom 'it may concern Be it known that I, Hiiivnr C. RinsnoL, a citizen of United States, residing at New York city, in the county of New York and State of New York, have invented new and useful Improvements in Concrete Building Forms, of which the following is a specification.

This invention relates to improvements in concrete building forms and is an iinpi'ovement over the formof my` invention shown and described in my eo-pending application Sr. No. 750,410, filed November 17th, 1924.

The principal object of the invention resides in the construction of a concrete form for use in pouring7 the outer wall of a building and which may bereversed and utilized for the pouring7 of the inner wall when forming a double wall structure hav ing an air space between the walls.

Other objects of the invention are to provide a cheap and inexpensive foi'm for the construction of hollow reinforced concrete walls; to eliminate the high labor costs in the assembling of the foi'm and to pour a one stoi'y double wall in two operations.

A. further object is the provision of a single form for the pouring irst of the outer ribbed wall, and which is rearranged in position for receiving the pouring of the inner wall, there being a novel means for supporting the form sections in spaced rela# tion with the outer wall dui'ing the pouring of the inner wall. i

lVith these and other' objects in view, vthe invention resides in certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claims, and are illustrated in the accompanying drawing, in which 1- Figure 1 is a horizontal sectional view showing the 'manner of forming the outer wall of a building.' y v Figure 2 is a similar view but showing the form section in position for forming the innei' wall.

Figure 3 is a horizontal sectional view through -a portion of the complete wall structure.

Figure lis an enlarged detail sectional view illustrating the means for holding the inner Vform sections in sealing engagement with theribs of the outer wall.

Figure 5 is a perspective view of one of the inner foi'm sections. l

Figure G is a perspective view of thev wall spacer. f

Figure 7 is a detailfperspective view ofl the bond structure'between' outer and yinner walls.

Referring moi'e particularly Vto the-drawing, the reference numeral 10 designates a' and an inner section ltwhich are held in spaced relation by brace rods 15. The outer section 13 includes a horizontal liner 16 any number of which may be provided and arranged in spaced relation Vand which engage vertical beams 17 carried'by the wall forming sections 18. The sections 18 are arrangedY in intimate' contact with each other to forni the outer wall of a mold cavity 19 formed by the space between the outerand inner sections 13 vand 14. Y

The inner section 14 incliudes a plurality of inner' wall` forming sections20 between the meeting edges of which one of thechannel members 10 is arranged. The ends ofthe sections 2O abut the flan ges'11 which prevent movement of the sections toward the outer section 13. The sections 2() are heldin position. by a horizontal liner 21jwhich is supported by brackets .22 carried by the channel members 10. A liners may be employed, but for the'ordinary height wall, three havebeen found to be sufficient. The liners 16 and 21 are held tight against the inner and outer wall forms by wires 22 which are looped about the liners and fastened securely as at 23 'for a distance approximating' the thickness of the wall to be formed.

Additional means is provided forholding the outer sections 18 in vertical position Any numberof these y ioo i Structure.

Which includes bolts 24 which extend through openings 25 in the body portion of the channel members and Which extend into the cavity 19. The bolts are inserted at suitable points along the length of the channel member and each receives aut -26 upon its threaded end. Each nut is formed With an eye 27 to which the free Hends of a Wire 28 are connected, the Wires extending through the outer Wall sections and around the meeting` beams 17. Y

Vhen removing the form after the formation of the outer Wall, the Wires 22 and 28 are. clipped adjacent the surface of the Wall to permit the liners 16 and 2l to be removed, after Which the bolts 24 are unscrevved from the nuts 26, thereby leaving the nuts and bolts of the Wires 28 in the Wall This noW leaves the channel members free whereby the Wall is clear of any form structure, it being understood that the outer Wall forming sections 1 8 have been previously removed with the liners 16 after the severing of the Wires 22 and 28.

`Figure 2 of the drawing clearly shows theV outer Wall structure in its completed condition wherein it will be noted that the brace rods 15, 4the twisted portions 23, portions of the Wire 28 and the nuts 26 are left in the wall for adding strength of the same and the saving of time in the removal of the fform. iIt Will be seen that the channel members serve to form spaced ribs 29 on the inner surface ofthe outer Wall designated by the -numeral A.

Rods 30 are anchored in the Wall during thelpouring of the same and extend through and beyond the ribs 29to provide a bond between fthe outer and inner Wall about to be described. i Before forming the inner Wall, lthe outer face of the ribs is provided with Water proofing material for preventing condensation kon' the face of thel inner Wall.

F rom the foregoing description it will be seen that the outer Vivall has Ebeen formed at whichV time the sealing strips 31 are attached to the vertical'beams of the sections 20 by `means of spring' clips 82 carried at spaced intervals upon .the length of said strip, and the sections in turn placed in alignmentivith the outerl face of the ribs. The strips are formed of sheets of rubber bent upon themselves and secured to provideyi'eldable portions for closing the space between the sections and the ribs and which are .wedged therebetween for frictionally supporting said vsections in set up position.

Spacers 38 are `interposed between each section 20 and the outer Wall and each is formedavith spaced parallel'rails 34 ,connected by blocks 35 rotatably mounted thereon.v These spacers kserve to brace the sections 2O during thepouring of the inner Wall.

The sections 18 previously employed for kpouring the exterior surface of the outer Wall are now placed in position and are held spaced by the rods 30 and spacers 36.

rllhe meeting beams 17 'receive clips 37 at spaced intervals for retaining the sections in tight contact and passing through each clip 37 is a bolt 38 which is threaded into the nut 26 anchored in the outer Wall and which formerly coacted With the bolt 24: for holding' the channel bars in position during the formation of the outer Wall. The form sections are nciv in position for receiving the pouring of the inner Wall which joins the ribs of the outer Wall and Which is bonded by the rods 30.

After the outer Wall has been poured and dried, the spacers 33 are removed by inserting an implement to rotate or destroy the blocks 35 to move them to a position parallel to the rails 8a Which permits'their easy removal. rEhe outer .sections 18 are noW removed by disengaging the bolt 3U from the nut 26 and by removing the clips 37. rlhe sections 2O are now free to be drawn upwardly from the air spaces Ll0 between the outer Wall A and the inner Wall B. V

The inner wall B is also reinforced by reinforcing rods di similar to the rods 31 in the outer wall. all been removed, a Wall such as shown in Figure 3 is provided and which is poured one storyhigh at a pouring thereby greatly reducing the labor costs and the use of eX- pensive forms noiv employed for the forination of a double Wall structure.
